Stop running this script in IE8 (client-side binding)

I am using client-side binding for my grid. When i have 50 records per page - which is not much - i get 1 "Stop running this script" messagebox in IE8. If number of records per page is more - it's customizable - i get event more such messageboxes.

The point is that execution time is not so long! Messagebox appears, even though user could wait this time without any problem!

In Mozilla everything is ok.

I have found that the problem is exactly filling the grid. When I comment the line
tableView.dataBind()

the page is shown without any javascript timeouts (but of course, with empty grid :) )

What could be done to get rid of this error?

RadGrid Can't access edited values on post back

Hello there,

I am using the radGrid and am updating values using edit forms.
On the code behind I couldn't get the updated values that i entered in the text-boxes. It always shows the old values. I have tried two approaches. using the ExtractValuesFromItem(dictonaryObject, editedItem) method and Fetching the data from each edited field individually through the auto-generated column editors, which both seems not to work. here is the markup for the grid and the code behind.
I would appreciate if somebody can help me out with this issue. I only have a day.

<tlrk:RadGrid ID="tlrkExpGrid" runat="server" CellSpacing="0"

GridLines="None" AutoGenerateColumns = "False"

OnUpdateCommand = "expDG_RowUpdating" >

</tlrk:GridEditCommandColumn>

<tlrk:GridBoundColumn DataField="ex_code" HeaderText="Code" UniqueName="ex_code" >

</tlrk:GridBoundColumn>

<tlrk:GridBoundColumn DataField="ex_name" HeaderText="Name" UniqueName="ex_name" >

</tlrk:GridBoundColumn>

<tlrk:GridBoundColumn DataField="DUNS" HeaderText="DUNS" UniqueName="DUNS" >

</tlrk:GridBoundColumn>

<tlrk:GridBoundColumn DataField="email" HeaderText="Email" UniqueName="email" ColumnEditorID = "emailEditor">

</tlrk:GridBoundColumn>

<tlrk:GridButtonColumn ConfirmText="Delete this Exporter?" ConfirmDialogType="RadWindow"

ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"

</Columns>

void expDG_RowUpdating(object source,Telerik.Web.UI.GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

string expCode = (editedItem["ex_code"].Controls[0] as TextBox).Text;

string expName = (editedItem["ex_name"].Controls[0] as TextBox).Text;

string duns = (editedItem["DUNS"].Controls[0] as TextBox).Text;

string email = (editedItem["email"].Controls[0] as TextBox).Text;

//this is the first approach

Hashtable newValues = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);

//this was the second approach trying to loop through each editor

string ee = t.Text;

GridEditableItem editedItem = e.Item as GridEditableItem;

How do you set minimum for Y-Scale (regular way does not work)

I have RadChart with 30 items on X scale. They all have values 0, and I am not showing it (visible=false). I am doing it because I would like to show empty char, but with correct scale (if you don't add any items, there will be red label in center with text about missing data).

So far, so good. But the problem is the chart Y scale goes by default from -50 to +50. And now is my question -- how do you change it, to go from 0, to default (50 is fine)?

I added in ascx file the tags

</PlotArea>

It does not work. So I added the equivalent of this in C# code, just after adding data. Still, no change. So how do you set this min value for Y scale?

Hierarchical Grid Cannot Find Column [ColumnName]

I have a grid that was working fine, but I wanted to add a detail table to it. When I did, it stopped working. It's saying that it can't find a column that I am 100% sure exists. I'm using an ObjectDataSource that returns an IList to bind the detail table with. Is there something I'm missing?

Altering data in listview during binding

I am trying to use a rad listview contol to display data from a SQL data table. When the data is loading (binding) I need to examine the data columns and perform some modifications to the data and replace the value in one of the data fields with the modified data. For example, there are three fields of data in the underlying query. Field 'A' contains 'abc'. Field 'B' contains '123'. Field 'C' contains an empty string. I want to concatenate the contents of Fields 'A' and 'B' and the place the results 'abc123' in Field 'C' which is defined in the listview layout.

I do these (and other) sorts of modifications to data regularly when using the rad grid. Can I do them when using your listview control as well?

When performing these operations in the grid, I use the "ItemDataBound" event and perform a test at the beginning of the event for "If TypeOf e.Item Is GridDataItem Then.....Else....End If" such as:

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

sLat = ""

sLong = ""

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

item("TextActive").Text = "Yes"

End If

End Sub

I have tried doing something similar in the same event for the RadListView control, but always get errors -- you may refer to the attached screen capture.

Is there a way to modify the data to appear in the radlistview similarly to what I am doing with the radgrid?

Thanks in advance!

FilterExpressions throws "index error" on postback

I have assigned multiple Group FilterExpressions to my ListView and am receiving the following error on postback:

"Index was out of range. Must be non-negative and less than the size of the collection."

Wondering if this indeed a bug or if I'm databinding my Listview incorrectly? I'm using the NeedDataSource function of the ListView to load the data. I have a button to "Apply Filter" that calls the RadListView1.Rebind method. I've tried to trace but the error is thrown before any databinding occurs on the Listview (something to do with the Viewstate for the FilterExpressions on the ListView)?

Thanks for any help,
Jason
